This handbook, now in a new, second edition, is an essential resource for scientists with an interest in the role of glycosyltransferases and related genes involved in the biosynthesis of glycoproteins, glycolipids, and proteoglycans. The first edition of the Handbook of Glycosyltransferases and Related Genes, published in 2002, contained descriptions of more than 100 mammalian genes by over 100 scientists who originally isolated and/or cloned these genes. Since then, there has been a growing body of evidence concerning the roles of glycosyltransferases, and additional glycosyltransferases...
